Narrow QRS Tachycardia in a Patient with Tachycardiomyopathy: What Is the Mechanism?

A 50‐year‐old female presented with incessant palpitation of 2 weeks duration. She was hemodynamically stable and there was no evidence of heart failure. A transthoracic echocardiogram showed mild left ventricular (LV) dysfunction with LV ejection fraction of 45%. Electrocardiogram (12 lead and rhyt...

Description
Summary:	A 50‐year‐old female presented with incessant palpitation of 2 weeks duration. She was hemodynamically stable and there was no evidence of heart failure. A transthoracic echocardiogram showed mild left ventricular (LV) dysfunction with LV ejection fraction of 45%. Electrocardiogram (12 lead and rhythm strip) was taken during the palpitation. What is the mechanism?
